Researchers transmitted individual photons over a 13-mile open-air route between Stony Brook University and Brookhaven National Laboratory, adding a wireless connection to a quantum network that the source says spans 161 miles across Long Island and the New York metropolitan area. The demonstration sent photons from an optical fiber to a rooftop detector through atmospheric turbulence. Specialized telescopes, mirrors and optical equipment guided the signal. The source describes the work as a demonstration rather than an operational communications service.
